Here is a new patch fixing most of your comments.

A couple of answers:

I'm a bit wary of this, because we can't test it properly.

Because 1e100 would raise OverflowError :)

Ok, I've replaced it with the following which should be ok:

    if (timeout >= (double) PY_TIMEOUT_MAX) [...]

Indeed it can (I sincerely hoped that nobody would care...).
I've replaced it with what might be a more appropriate construct.
Please note that behaviour is undefined when microseconds exceeds the max timeout, though (this is the low-level C API).
